instruNet i60x provides
16se/8di Voltage Input Channels with extremely
accurate 24-bit A/D
Converter29.
Alternatively, one might consider the larger i555
card cage with 8 to 256 channels.

Why so accurate? It was designed in 2016; whereas many competing
products are older.
The i601
tiny standalone USB device provides ±36V bank electrical isolation; whereas the less costly
i600
directly connects I/O signal ground to computer ground via USB cable.
Digitize at a maximum sample rate of 160K samples/sec for 1 channel, 12Ks/sec/ch for 2 channels,
6Ks/sec/ch for 4 channels or 3Ks/sec/ch for 8 channels.
Very low internal noise,
as shown above
(2μVrms, 1Ks/sec, ±20mV range)
